MACHINE FOB, GRADUATING THE VELOCITY OF MOVING BODIES.

Specification of Letters Patent No. 1,928, dated January 5, 1841.

To all whom t may concern.'

Be it known that l, EDwiN W. JACKSON, of the city and county of Albany and State of New York, have invented a new and useful Machine for Graduating the Velocity of Moving Bodies, called the Graduating Operator; 7 and l do hereby declare that the following is full, clear, and exact description of the construction and operation ot the same, reference being had to the annexed drawings of the same, making part of this speciiication, in which- Figure 1 is a perspective, and sectional view of the machine, the wheel being` divested of its end pieces and its outer cylindrical band. The parts marked A are permanent partitions placed at equal distance apart and all of one forni and diameter attached at C to the cylinder E, each one having a breach or opening at D and E which are either shut or open according to the situation of the sliding doors, marked F, all

being of one form and dimension and atv equal distance apart and lirmly affixed to the band G, which is suffered to slide backward and forward through each partition at H, and is connected to the revolving axle or rod J, by the cord K, which passes through a hole in the center of the said rod and there fastened. Two or three turns are made around the rod and the ends of the cord firmly secured to the band G, at L and M. To the upper end of the rod is attached the pointer N, which, upon being turned, will force around the band G, with the sliding doors F, either opening or closing the breaches at D and E.

Fig. 2 is a view of the structure of the machinery, when divested of the parts belongingv to the index, A being the permanent partitions, B the cylinder to which they are attached, D and E the breaches to be opened or closed by the sliding doors, H the apertures through which the band G slides, O and P apertures in each partitio-n to prevent the quicksilver (or whatever the wheel may be loaded with) from hanging back when it is requisite for the retarding power to be as light as possible.

Fig. 3 is a view of the machinery of the index, F the sliding doors, G the band to which the sliding doors are attached, J the rod or axle to which the co-rd K is attached, L and M the points in the band where the ends ofthe cord are fastened.

The following additional drawing, Fig. 4,

of another mode ot applying the same principles is introduced, being more fully explanatory of the method, by which a general graduating and regulating power is produced. It differs in form from the mode above described, having no index, but the principle of operation is the sam-e. The partitions are all ot one size and form; they lie permanently attixed between two cylinders, the outer one marked A and the inner one B, the loading having a passage only from one receptacle to another through the breaches in each partition C and D. The wheel is here represented as loaded. The receptaclesl E, F, Gr, H, I, J, and K, are charged, while those on the opposite side are empty; consequently as the wheel is traversing down an inclined plane (as represented by the line M) it traverses the empty side first and its velocity is governed by the size otthe breaches in the partitions which suffers the weight gradually to pass from one receptacle to another.

The variety of forms which can be adopted tor the receptacles of the weight in this machine are indetinite. They vary from a hollow sphere to any form capable of retarding the gravitation of the weight within, which may consist of quicksilver, shot, gravel, sand, water, or any other weight capable of passing through the outlets.

The operation of this machine causes unit'ormity in the velocity of motion and is applicable as a regulator to any purpose requiring moderated or graduated velocity. t is by construction susceptible of increase or diminution of power to meet any contingency and of an indefinite variety of useful applications. The inventor has contemplated the following among many others, viz: As a regulator to the velocity of freight descending by inclined planes either by using two parallel inclined planes one for the train of cars and the other for the graduating wheel both attached to the ends of a chain passed around a stationary pulley at the head of the inclined planes so that as the loaded train descends on one side the graduating wheel ascends on the other side and when the load is discharged the graduating wheel descends, drawing up the empty cars, or in vehicles furnished with wheels of the above described construction, or by a connection through the medium of the chain with a stationary wheel at or near the pulley or fulcrum, or any other inode convenient to the application contemplated. As a stationary power regulating the descent of the merchandise or other Weights, a substitute for the Wheel and axle in com-mon use. As a graduator of motion for the admeasurement of time. As a preventive to undue speed in vehicles drawn by Festive animals.

That I claim as my invention and which I desire to secure by Letters Patent is- 1. The inode of graduating the velocity of moving bodies by means of a changeable Weight such as quicksilver, Water, sand, shot, cc., contained in receptacles of any given form arranged around or between two con- EDWIN W.
